Update require.intellisense.js

I spent ages researching this and finally came up with this file achieving intellisense throughout my project. I'm not sure what the setTimeout was achieving nor calling onScriptLoad, what doesn't happen now I've not called it? 

In version I've forked from requirejs my test examples did not work at all, perhaps partly because my requirejs.config is complicated and needed loading at the right time, also the code did not support the `requirejs` global. I guess this project needs some tests. I tried very hard to get Visual Studio to let me know the path of a javascript path it has loaded so that defines can be anonymous but I believe it can't be done.

    define('foobar', ['res', 'jquery'], function (res, $) {
        // res and $ have intellisense here
    }

    requirejs(['res', 'jquery'], function (res, $) {
        // res and $ have intellisense here
    }
